1.2 Overview The TC-MIDI series was designed specifically for high cooling capacities and high ambient temperatures. The TC-MIDI+ series was designed specifically for the requirements in so-called automated measuring systems (AMS) according to EN 15267-3. The series connection of the heat exchangers will cool in two cycles to minimise wash out effects.

TC-MIDI (+) 2.2 General hazard warnings The equipment must be installed by a professional familiar with the safety requirements and risks. Be sure to observe the safety regulations and generally applicable rules of technology relevant for the installation site. Prevent malfunctions and avoid personal injuries and property damage.
TC-MIDI (+) 3 Transport and storage Only transport the product inside the original packaging or a suitable alternative. The equipment must be protected from moisture and heat when not in use. It must be stored in a covered, dry and dust-free room at a temperature of -20 °C to 60 °C (-4 °F to 140 °F).
TC-MIDI (+) 4 Installation and connection 4.1 Installation site requirements The unit is only intended for wall-mounted use in enclosed areas. Adequate protection from the weather must be provided when used outdoors. Install the unit leaving enough room below the cooler to discharge the condensate. Leave room above for the gas supply. Be sure to maintain the approved ambient temperature.
TC-MIDI (+) 4.2.4 Sample gas pump connection gas lines (optional) On coolers ordered with attached sample gas pump these are already installed and wired. Add-on parts ordered at the same time are already installed and connected to the sample gas pump. The sample gas pump may be installed both below and next to the cooler.
TC-MIDI (+) On glass heat exchangers the correct position of the seal is important when connecting the gas lines (see image). The seal con- sists of a silicone ring with a PTFE sleeve. The PTFE side must face the glass thread. Glass PTFE 4.3 Electrical connections...
TC-MIDI (+) Connection via plug The device is equipped with connectors according to EN 175301-803 for mains and status output. If the cables are mounted prop- erly, they cannot be interchanged. Please make sure that the connectors are remounted correctly after connecting the cable. The following figures show the pin assignment with respect to the numbers printed on the connector.
